In materials science, the Burgers vector, named after Dutch physicist Jan Burgers, is a vector, often denoted as b, that represents the magnitude and direction of the lattice distortion resulting from a dislocation in a crystal lattice.
The magnitude and direction of slip are represented by the Burgers vector, b. An external force makes parts of the crystal lattice glide along each other, changing the material's geometry. A critical resolved shear stress is required to initiate a slip. [2]
The dislocation has two properties, a line direction, which is the direction running along the bottom of the extra half plane, and the Burgers vector which describes the magnitude and direction of distortion to the lattice. In an edge dislocation, the Burgers vector is perpendicular to the line direction.
The complete transit is accompanied by creation of matrix-precipitate surface area of approximate magnitude =, where r is the radius of the particle and b is the magnitude of the burgers vector. The resulting increase in surface energy is E = 2 π r b γ s {\displaystyle E=2\pi rb\gamma _{s}\,\!} , where γ s {\displaystyle \gamma _{s}} is the ...
For a three dimension dislocations in a crystal, considering a region where the effects of dislocations is averaged (i.e. the crystal is large enough). The dislocations can be determined by Burgers vectors. If a Burgers circuit of the unit area normal to the unit vector has a Burgers vector
Recent court orders slowing down or indefinitely blocking President Donald Trump’s policy blitz have raised the specter that the executive branch might openly flout the federal judiciary and ...

If a shear stress is exerted on the slip plane then a force =, where b is the Burgers vector of the dislocation and x is the distance between the pinning sites A and B, is exerted on the dislocation line as a result of the shear stress.
